_Isa Lake_ (8,250)--L: 6--1893--N. P. R. R.--For Miss Isabel Jelke, of Cincinnati. _Jackson Lake_ (6,000)--U-W: 6--Date unknown.--For David Jackson, a noted mountaineer and fur trader, and one of the first three partners of the Rocky Mountain Fur Company. This lake was discovered by John Colter and was named by Clark _Lake Biddle_, in honor of Nicholas Biddle, who first gave to the world an authentic edition of the journal of the celebrated Lewis and Clark Expedition. _Jenny Lake_--South of Leigh Lake and off the map.--1872--U. S. G. S.--For the wife of Richard Leigh. She was a Shoshone Indian. _Leigh Lake_--W: 5--1872--U. S. G. S.--For Richard Leigh ("Beaver Dick"), a noted hunter, trapper, and guide in the country around the Teton Mountains. The nickname "Beaver Dick" arose, not from the fact that Leigh was an expert beaver trapper, but on account of the striking resemblance of two abnormally large front teeth in his upper jaw to the teeth of a beaver. The Indians called him "The Beaver." _Lewis Lake_ (7,720)--O: 7--1872--U. S. G. S.--For Captain Lewis of "Lewis and Clark" fame. "As it had no name, so far as we could ascertain, we decided to call it Lewis Lake, in memory of that gallant explorer Captain Meriwether Lewis. The south fork of the Columbia, which was to have perpetuated his name, has reverted to its Indian title Shoshone, and is commonly known by that name, or its translation, Snake River. As this lake lies near the head of one of the principal forks of that stream, it may not be inappropriately called Lewis Lake."--Bradley.[CN] [CN] Page 249, Sixth Annual Report of Dr. Hayden. _Loon Lake_ (6,400)--R: 3--1885--U. S. G. S.--Characteristic. _Lost Lake_ (8,500)--M: 7--1885--U. S. G. S.--Characteristic.--This is probably Norris' Two-Ocean-Pond, and is doubtless also the lake referred to by Hayden in the following paragraph from his report for 1871: "We camped at night on the shore of a lake which seemed to have no outlet. It is simply a depression which receives the drainage of the surrounding hills. It is marshy around the shores, and the surface is covered thickly with the leaves and flowers of a large yellow lily."--Hayden. _Madison Lake_ (8,250)--N: 4--1872--U. S. G. S.--Head of the Madison River. "A small lake, covering perhaps sixty acres, occupies the southern end of the [Firehole] valley, where it bends to the eastward; and as the ultimate lake source of the Madison River, is the only proper possessor of the name 'Madison Lake.'"--Bradley.[CO] [CO] Page 243, Sixth Annual Report of Dr. Hayden. _Mallard Lake_ (8,000)--L: 5--1885--U. S. G. S.--Characteristic. _Mary Lake_ (8,100)--J: 7--1873--Tourist Party.--Circumstance recorded by Rev. E. J. Stanley, one of the party, and author of the book "Rambles in Wonderland," describing the tour. The following extract is from his book:
